How to Choose a Power Bank

Power banks and portable chargers seem to be quite powerful electronic gadgets. You do realise that it’s simply a large battery, don’t you? To be honest, you’re totally correct about it!  This is an all-inclusive beginner’s guide regarding how to choose a power bank, so if you’re already familiar with certain topics, feel free to skip ahead to the parts that interest you the most.

What can be charged with power banks?

These power banks are capable of providing power to almost any electronic device, from laptops and portable gaming consoles to smartphones and tablets. On the other hand, they are mainly intended for use with portable communication and media devices.

 

The majority of them can charge a smartphone many times, and a few of them have more than one outputs, which allows you to charge numerous devices at the same time. You could charge two cellphones at the same time, or a smartphone and a tablet, or even a tablet and a laptop.

 

It may come as a surprise to hear that in most cases, they can charge tablets in addition to other gadgets like portable speakers, wireless headphones, and small cameras. The Nintendo Switch and other portable gaming devices may be charged using a variety of different power banks that support USB-C.

 

Some versions even have enough power to operate computers, although we wouldn’t advise doing so unless you were stuck somewhere without access to an electrical devices or had forgotten your laptop charger. It comes in useful in a pinch, but it is not intended to serve as a replacement for your regular external power source.

 

When looking for a new power bank, the most important factors to take into consideration are its size, form, weight, and capacity. A beautiful clear representation of the amount of available power is also helpful; some versions show this information on a digital display rather than using bars (for example, “80 percent is still available”).

How to Pick a Power Bank

A simple power bank that has two USB connections so that you may simultaneously charge numerous devices.

 

When it comes to choose a power bank, there are three primary specifications that you should be aware with.

The capacity of the power bank refers to the amount of energy that it can store and is often measured in milliamp hours (mAh).

 

The quantity of power that must be supplied in order to fully recharge the power bank itself is referred to as the input.

 

Output refers to the quantity of power that may be transferred from the charger to other electronic devices.

 

The term “port” refers to a certain kind of socket or connection. The most common method of recharging a power bank these days is via a USB-C connector; however, most of the power banks still have the capability of delivering power through a USB-A connection, which uses the older kind of USB plug.

 

Size Vs Power

Your portable power bank is a tradeoff in the same way that everything else in life. You will need to strike a balance between the amount of electricity you need and the size of the brick you are willing to transport with you. A little charger that fits in your pocket isn’t going to keep you running for a week in the wilderness.

 

Power Banks with Capacity of 3000-9000 mAh

Power Banks with a capacity of 3000-9000 mAh may provide one or even two full charges to a mobile device, making them an excellent choice for an overnight trip. They are also available in hundreds of different colours, forms as well as the sizes, giving you the ability to either show it out or conceal it. In most cases, a power bank of this size will allow you to slowly charge your tablet, but there is a chance that it will not fully charge. On the other hand, laptops and anything larger are out of the question.

Power Banks with Capacity of 9000-15000 mAh

Power Banks with a capacity of between 9000 and 15000 mAh are suitable for providing at least two or three full charges to a smartphone and one full charge to a tablet. Because they are often too large and heavy to fit in a pocket, you will need to transport them in a bag if you are always on the go. Within this range, it is possible that you will be able to begin charging laptops, but this will depend on the output of the power bank.

Power Banks with Capacity of 15000+ mAh

Large Power Banks with a capacity of 15000 mAh or more have an effectively endless capacity both in terms of the number of charges they can provide and the variety of electronic devices they can power. These power banks can keep your phone charged for at least a week and can provide power to a wide variety of electronic devices, including laptops, well… anything!

 

What kind of capability do I require?

The capacity, which is measured in milliamp hours (mAh), provides a general estimate of the charging capabilities of the power bank. The greater the figure, the more power the power bank can supply to your device until it runs out of charge. You should look for a power bank that can provide your smartphone at least two full recharges before it has to be recharged again, since this should give you coverage for one or two days at a time before it needs to be recharged again.

Size and Weight

The mAh capacity is often accompanied by a rise in both size and weight. Although a model with 20,000 mAh can seem like a useful alternative, it’s possible that it will be too bulky to fit in your pocket or backpack.

 

Consider purchasing a pocket-sized power bank with a capacity of at least 6000–10,000mAh if you want to be able to keep your phone charged while attending a one-day music festival, picnic, or going out for the evening. Larger capacity versions may be necessary in other contexts, such as when you are going on a trek that will keep you off from the power grid for many days, but they are often too bulky to fit in most pockets.

 

It is always advisable to have a little of additional capacity so that you can make sure the gadget receives a full charge. The capacity of the power bank must be slightly higher than that of the item that is going to be charged in order to ensure a full charge.

You may get a good notion of what is required by looking at the chargers that are given to you along with the device. There are many little USB gadgets that just need a charging current of around half an amp, whereas phones may require approximately an amp, and tablets may require approximately 2.5 amps.

 

Quickly Charged

If something has the capacity to be charged quickly, then it will need a higher current, maybe three amps. It is important to take notice of this development since more and more gadgets now have this feature.

 

In most cases, the power banks will specify the maximum amount of current that they can provide. The longer it takes to charge the gadget, the lower the maximum current that it can give, the longer it will take. There are numerous outputs available on some bigger power banks; each output will be defined, and the specifications are often listed on the power bank itself.

Be aware that if a device has several outputs, it may not be able to provide the maximum current to all of the outputs at the same time. This is something you should keep in mind.

 

If you want to shorten the amount of time it takes to charge your device, you should select a power bank that has a high output current. If the phone or gadget cannot take the maximum current, don’t worry, it will just take what it can manage.

 

Lithium-ion & Lithium Polymer

There are two primary battery technologies that are employed with power banks, and they are lithium-ion and lithium polymer. Lithium-ion is the more common of the two. There are a few subtle distinctions to be made, despite the fact that both are fairly comparable in the majority of regards.

Lithium-ion batteries have a substantially cheaper cost than lithium-polymer batteries, in addition to having a higher power density than those batteries. The memory effect, in which batteries gradually become more difficult to charge as time passes, is absent from lithium-ion batteries.

In general, lithium-polymer batteries are more durable and flexible than other types of batteries, particularly when it comes to the size and form of their construction, and they often have a longer shelf life.

 

Not all power bank specs will indicate if the power bank has lithium ion or lithium polymer batteries, but some will.

 

Connectors for charging: Despite the fact that the output on virtually all power banks is a USB Type A, which is the big USB connection that is used to interact with USB chargers, flash memory drives, and other similar devices, the connector that is used to charge the power bank is different.

 

Common Connectors for Power Bank

It is often a micro-USB, although it may also be a mini-USB on occasion. However, some newer models have begun include a lightning connection, which allows the device to be charged using an Apple charger and an Apple lead. This helps to reduce the number of different leads that are required.

 

How to Charge the Power Bank

It is important to keep in mind that you will need to charge the power bank itself before you can use it. The more the capacity, the greater the amount of time it will take. If the power bank has a capacity of 5000 milliampere-hours (mAh), then it will take five hours to charge.

However, the charging process will take a little longer than five hours because not all of the charge that enters the power bank is converted to stored charge. There is an efficiency factor of possibly 80% or more, so the charging process will take longer.

 

Leads: When purchasing a power bank, it is imperative that you do not forget to purchase the leads. Not all power banks come with leads, either for charging devices from the power bank or for charging the power bank itself. Leads may be used to charge either the item being charged or the power bank itself. It’s possible that some power banks, especially the more affordable ones, won’t come with leads; in that case, you’ll need to supply your own.

How to Choose a Power Bank for Trip

A little less than ten years ago, when printed guidebooks were all the rage, many travelers had never ever heard of power banks (portable battery chargers), much alone travelled with one. Today, more and more people are choosing power banks to bring them on their trips.

 

This is due to the fact that portable power banks have only been around for a very short period of time and have only in the last few years gained broad popularity. Simply said, there was never an urgent need for them to exist in the past.

 

But in the modern world, e-guidebooks have started to replace traditional guidebooks, and a lot of travelers are carrying these digital travel guides on their smartphones and tablets and reading them there.

 

E-books don’t have any weight, so it doesn’t matter how many you put onto your device; the weight of the gadget won’t change, no matter how many e-books you store on it. This is an approach that has a lot of merit.

 

And the value of gadgets like smartphones and tablets for travelling extends well beyond their capacity to carry and display digital guidebooks for convenient reading while on the road. This is only one of the many ways that these devices may be beneficial.

 

Reasons to use the Smartphones by Travelers

  • Using a variety of different navigation applications, one may get about towns and cities as well as identify hotels, transportation hubs, restaurants, sights, attractions, ATMs, petrol stations, and other local amenities.
  • Maintain a record of where they are when they are on the bus or train to ensure that they do not arrive late at their destination.
  • Make sure you don’t get lost when hiking in the mountains or in other isolated regions.
  • When things go serious, you should contact the emergency services.
  • Make reservations for hotels, trains, buses, and excursions.
  • Place your orders for taxis and ridesharing taxis here.
  • Converting currencies before changing money can help you avoid being ripped off.
  • I am fluent in a number of different languages, both spoken and written.
  • capture memories of trips by way of photographs and films.
  • Make audio recordings of the remarks made by tour guides at the various sights.
  • Check the balances of your bank accounts.
  • record trip expenditures
  • Talk things over with your loved ones and close friends.
  • Post updates about your trip on various social media platforms.
  • Use a two-factor authentication method to verify both your account logins and your transactions.
  • carry out a wide variety of additional duties

 

Some of us are even more dependent on our mobile devices than we have ever been before when travelling as a result of the rising popularity of electronic boarding permits at airports. These passes are provided on the screens of mobile devices.

And if you ever buy an electronic ticket for a bus or train, you may use your smartphone to prove to the inspector that you are in possession of a legitimate ticket for the trip.

To summarise, the modern-day travelers has grown very reliant on his smartphone in order to perform well when on the road, and he requires that it remain operational at all times.

 

All of these improvements appear to be coming at the expense of the battery life of smartphones, despite the fact that phones are growing thinner, more powerful, and more versatile.

 

And unfortunately, the batteries in smartphones have a propensity to expire precisely at the time when you need them the most as a traveler. This might happen, for example, when you first arrive in a new city after a long trip by bus or train and have no idea where to locate a hotel.

 

There is no assurance that you will be able to keep your device charged either while you are at the airport or while you are in the air. Even charging stations are not provided at certain airports, and many aircraft do not have power outlets available for passenger use.

 

In many underdeveloped areas, even in some of the largest cities, power outages that last for many hours or even days at a stretch are normal. When these outages occur, the clock is ticking before you wind up with a dead battery.

 

Considerations before Choosing a Power Bank for travelling

When attempting to choose which power bank is best for travelling, there are a number of key considerations you need to make. Before we show you the list of power banks that we suggest, we will first go over the most significant of these aspects.

If you are aware of this information, you will be able to make your own decision about which power bank to buy without being swayed or influenced by anyone else who has a covert agenda.

 

Capacity

When looking to purchase a power bank, the capacity of the device is perhaps the single most significant consideration to make.

When you travel, it is important to bring along a power bank that has a large capacity, as there will likely be times when you won’t be able to access a working power outlet for an extended period of time (such as during 40-plus hour long train journeys, where the power outlets on the train refuse to work i.e india). In these cases, you won’t be able to charge your electronic devices.

 

High Capacity Power Banks

A Power Bank with a lower capacity may not always be sufficient. It is preferable to have more capacity than to need it and not have it available; in other words, it is better to have it than to need it and not have it.

 

If you simply want to use the power bank to charge your smartphone, we normally suggest purchasing a power bank with a nominal capacity of 10,000 mAh. This amount of energy is sufficient to completely charge the majority of smartphones between three and four times, depending on the model (and most tablets 1- 1.5 times).

 

When going on a trip, it’s a good idea to invest in a power bank that has a capacity that is three to four times more than the one that is built into your smartphone. If you want to utilise a power bank to charge a tablet or another gadget with a bigger battery, you will need one that has a capacity that is far more than what you now have.

 

However, the most significant reduction in capacity is caused by the process of voltage conversion that takes place within the power bank.

 

In order to determine the actual amount of energy that can be stored by a power bank, it is necessary to take into account not only the mAh value, but also the voltage at which it can be delivered.

 

Weight

Because many airlines have quite stringent weight limitations on hand baggage that is permitted to be brought on board, and many chargers are not pocket-friendly, travelers who are just bringing their carry-on bags with them need to be especially mindful of the weight of a power bank.

 

Even while a power bank may not be very heavy by itself, it nonetheless has the potential to be the last obstacle that causes the camel’s back to buckle.

 

A heavy brick in your pocket is not only annoying, but it also makes it necessary to tighten your belt and drawstrings on your pants in order to prevent your drawers from falling down around your ankles. Additionally, if you try to run with the brick in your pocket, it will bounce around annoyingly inside your pocket.

 

Size

A power bank that is more compact may be slipped into pockets, pouches, and compartments of a backpack with relative ease, freeing up more room in these locations for the storage of other essential things.

 

A power bank that is tiny may also fit more readily in your trouser pockets, which makes it easier to use your phone as usual when you are moving about while it is charging from the battery pack that is in your pocket (with the cable running between them).

 

When it comes to this topic, the golden rule is that smaller is better, provided that the capacity is enough for your particular requirements. You won’t have a need for a power bank with a large capacity if you travel with just a few electronic gadgets and use them sparingly.

 

Design

Your own tastes will play a significant role in determining the power bank design that you ultimately choose with; nevertheless, design choices may also have significant repercussions in the real world and can have an effect on how user-friendly a product is.

 

Although power banks can come in a variety of shapes, the majority of them are roughly rectangular in outline. Power banks can more infrequently be found in the shape of a cylinder, an oval (in cross-section), a cube, or even something completely bizarre. There is even a power bank in the shape of a fiery chilli pepper that we have seen.

 

A power bank that has a design that is rather streamlined makes it simple to slide it into a confined pocket or the sleeve of a backpack; nevertheless, we find that versions that are slightly bulkier still fit just well in the pockets of our spacious pants.

 

Not only do rounded edges look elegant, but they also make it possible for the power bank to be held comfortably in one hand. You will frequently find yourself holding both the power bank and the phone in one hand when the phone is charging and you need to use it. Rounded edges not only look elegant, but they also make it possible.
